INA296A2QDGSRQ1

Overview

The INA296A2QDGSRQ1 is a bidirectional, ultra-precise current sense amplifier from the Texas Instruments INA296A series. It operates with a common-mode voltage range of -5 V to 110 V and features a gain bandwidth product of 1.1 MHz. The device offers a fixed gain of 20 V/V, an input bias current of 45 uA, and an input offset voltage of 3 uV. It has a maximum supply voltage of 20 V, minimum of 2.7 V, and typical operating supply current of 2.5 mA. The gain error is specified at 0.002%, with a CMRR of 150 dB. It is housed in an SOIC-8 package, rated for AEC-Q100 qualification, and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Bidirectional measurement capability supporting high-side or low-side sensing configurations
• Ultra-precision architecture ensuring minimal signal distortion through low offset voltage and high CMRR
• Automotive-grade reliability certified under AEC-Q100 standards for harsh environment operation

Applications

• Electric vehicle battery management systems
• Motor control circuits in automotive applications
• High-voltage current monitoring in industrial power supplies

Procurement Notes

Verify the specific suffix 'DGSR' confirms the SOIC-8 tape-and-reel packaging format. Confirm AEC-Q100 qualification status matches project requirements. Ensure the fixed 20 V/V gain aligns with system resolution needs. Check moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this component when bidirectional current sensing is required in high common-mode voltage environments up to 110 V. The 20 V/V gain suits applications needing moderate amplification without external resistors. Consider the 1.1 MHz bandwidth for dynamic load responses. Verify thermal performance within the SOIC-8 package constraints.

Part Context

Part of the INA296A family of ultra-precise current sense amplifiers designed for automotive and industrial use. Shares core specifications like bandwidth and common-mode range with variants differing in gain and package type. Provides a robust solution for precise current monitoring where accuracy and speed are critical.

Replacement Considerations

Check INA296A3QDRQ1 for similar performance in SOIC-8 with different gain. Evaluate INA296A4QDRQ1 for alternative gain options in the same package. Review non-automotive INA296A variants if AEC-Q100 certification is not mandatory.
